Because of genetic variation, a species of beetle has two different body colors, red and green. this species exists in a grassy environment
that's mostly green. a new species of bird that eats these beetles enters the area. arrange the steps of natural selection in the correct order.

green beetles and red beetles exist in the
environment.

green beetles pass on their color trait to
future offspring

birds that eat the beetles move into the
environment.

red beetles are eaten by birds, but green
beetles aren't eaten.

the entire population of beetles
eventually becomes green in color.

The investiture controversy began as a power struggle between pope gregory vii (1072–85) and henry iv, holy roman emperor (1056–1106).[2] a brief but significant struggle over investiture also occurred between henry i of england and pope paschal ii in the years 1103 to 1107, and the issue played a minor role in the struggles between church and state in france, as well.by undercutting the imperial power established by the salian emperors, the controversy led to nearly 50 years of civil war in germany, and the triumph of the great dukes and abbots. imperial power was finally re-established under the hohenstaufen dynasty. historian norman cantor:
